A federal lawsuit filed in May claims Lil Wayne didn't have permission to sample a song by singer Karma-Ann Swanepoel.
The suit says Lil Wayne's record label, Cash Money Records, tried but failed to negotiate a license to use Swanepoel's song "Once" before millions of people downloaded the rapper's song "I Feel Like Dying."
A court filing Tuesday by Lil Wayne's attorneys asks a judge in New Orleans to extend a Friday deadline for turning over documents requested by lawyers for the company that published Swanepoel's song.
